Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of metal roof repair, and in particular relates to a transposition connection device suitable for reinforcing a profiled metal sandwich roof. Background Art
[0002] Over the past 30 years, with the rapid development of society, corrugated metal sheets have been widely used in industrial plants and public buildings due to their low cost, easy shaping, and efficient construction. For applications requiring special insulation, heat insulation, and fire protection, the use of special chemical materials between the layers of metal sheets is often used to achieve these requirements, with good results.
[0003] Over time, exposed to sunlight, rain, and heat, many metal panels develop a degree of rust. The most common treatment is to periodically apply anti-rust paint to the panels. Depending on the material used, the duration of corrosion protection provided by coatings varies. However, once rust reaches a certain level, replacement becomes necessary. Replacing the roof of industrial plants, public buildings, and other structures is often a significant undertaking, disrupting the building's functionality.
[0004] To address these issues, two approaches are often employed. First, adding a new roof, provided the building structure meets its structural requirements and does not affect the use of the existing roof. This approach is limited in that the need for a new roof is often not considered during building design. Adding a new roof exposes it to significant loads from wind, snow, and rain, making retrofitting difficult. Second, after the roof is treated, a secondary drainage solution is installed above the interior ceiling. This approach is limited in that the secondary drainage solution is a concealed project, and any problems with it pose a significant risk to normal indoor use. Summary of the Invention
[0005] In response to the problems in the above-mentioned prior art, the utility model provides a transposition connection device suitable for reinforcing a corrugated metal sandwich roof. Its technical solution is: it includes a main purlin and a metal sandwich roof, the metal sandwich roof is mounted on the main purlin, a plurality of transposition components are provided on the surface of the metal sandwich roof, a secondary purlin is provided above the transposition component, and a metal panel base is provided on the secondary purlin.
[0006] As a preferred solution, the transposition members are arranged on the tile ridges of the metal sandwich roof, and the bolt holes on the tile ridges are evenly arranged, and the transposition members in adjacent rows are arranged in different directions.
[0007] As a preferred solution, the metal sandwich roof and the transposed member are fixedly connected by arranging a first bolt on the bolt hole of the transposed member, and the first bolt passes through the metal sandwich roof to the main purlin.
[0008] As a preferred solution, an insulating gasket is provided at the connection between the first bolt and the main purlin.
[0009] As a preferred solution, the transfer component is fitted with the tile ridge of the metal sandwich roof.
[0010] As a preferred solution, the secondary purlin is fixedly connected to the metal panel base through a second bolt, and the metal panel base is fixedly connected to the new roof.
[0011] Beneficial effects of the utility model:
[0012] (1) The device will not damage the existing roof system. The device is implemented by connecting to the existing bolt holes on the ridge of the metal sandwich roof tile, causing almost zero damage to the existing roof;
[0013] (2) The implementation of this device does not require the demolition of the existing roof. Instead, the transposed components and secondary purlins are installed on the existing roof. The construction speed is fast, the installation is convenient, the operation is simple and the safety is high, which reduces the construction cost and difficulty.
[0014] (3) The device does not need to be suspended for indoor use during the implementation process, will not have adverse effects on the interior of the building, and will reduce the economic losses caused by suspending the use of the building during the construction process.

[0021] The present invention will be described in further detail below based on the accompanying drawings and specific embodiments.
[0022] Example
[0023] like Figure 1-5 The figure shows a transposition connection device suitable for reinforcing a corrugated metal sandwich roof, comprising a main purlin 1 and a metal sandwich roof 2. The metal sandwich roof 2 is mounted on the main purlin 1, and a plurality of transposition members 3 are provided on the surface of the metal sandwich roof 2. A secondary purlin 5 is provided above the transposition member 3, and a metal panel base 6 is provided on the secondary purlin 5.
[0024] Furthermore, the transposed member 3 is arranged on the tile ridge of the metal sandwich roof 2, and the bolt holes on the tile ridge are evenly arranged to avoid secondary damage to the metal sandwich roof 2 and increase the risk of water seepage. The transposed members 3 in adjacent columns are arranged in different directions. The purpose of this arrangement is to prevent the transposed members 3 from being damaged due to eccentric force caused by negative wind pressure.
[0025] Furthermore, the metal sandwich roof 2 and the transposed member 3 are fixedly connected by arranging a first bolt 4 on the transposed member bolt hole 301 , and the first bolt 4 passes through the metal sandwich roof 2 to the main purlin 1 .
[0026] Furthermore, an insulating gasket 401 is provided at the connection between the first bolt 4 and the main purlin 1. The insulating gasket 401 plays a certain role in force buffering and reducing the risk of galvanic corrosion between different metals when the new roof is subjected to negative wind pressure as a whole.
[0027] Furthermore, the transfer member 3 is fitted with the tile ridge of the metal sandwich roof 2. When the transfer member 3 receives the dead load or live load transmitted by the new roof, the pressure is evenly dispersed to avoid concentrated damage.
[0028] Furthermore, the secondary purlin 5 is fixedly connected to the metal panel base 6 by a second bolt 7, and the metal panel base 6 is fixedly connected to the new roof. The compressive stress borne by the new roof and the outside is transmitted to the secondary purlin 5 through the metal panel base 6 and then to the transferred component 3, and finally to the main purlin 1 through the metal sandwich roof 2.
[0029] The above-mentioned device is used in the following process: the original bolts on the metal sandwich roof 2 are removed, and the transposed components 3 are set at the bolt holes. The transposed components 3 of adjacent rows are set in different directions. The transposed components 3 are fixed to the metal sandwich roof 2 by the first bolts 4. The first bolts 4 pass through the metal sandwich roof 2 to the main purlin 1. The insulating gasket 401 is installed at the connection between the first bolts 4 and the main purlin 1. Then, the secondary purlin 5 is laid on the transposed components 3, and the connection is welded. Then, the metal panel base 6 is set on the secondary purlin 5, and the new roof is fixedly connected to the metal panel base 6 to complete the installation.
